HelloThanks for writing to us.From your description the most possible causes in my opinion are-1. Erythema multiforme.2. Dermatitis- due to skin infection, allergy,etc.3. Dry skin- Xerosis.4. Heat rash. A direct examination by a dermatologist is the best way to get it diagnosed.Most simple rashes improve with gentle skin care and avoiding irritating substances. You can help the improvement by * Avoid scrubbing your skin. * Use as little soap as possible. Use gentle cleansers instead. * Avoid applying cosmetic lotions or ointments directly on the rash. * Use warm (not hot) water for cleaning. XXXXXXX dry, don't rub. * Eliminate any newly added cosmetics or lotions. * Leave the affected area exposed to the air as much as possible. * Try calamine medicated lotion. * Hydrocortisone cream (1%) is available without a prescription and may soothe many rashes.The patches usually take 5-7 days to disappear.If the patches become more of purple rather than red then you must consult a dermatologist immediately.

I hope my answer and recommendations are adequate and helpful. Waiting for your further follow up queries if any.Regards.

This makes sense to me, yet I just want to clarify something further. The blotches are really more like spots (they look like freckles). Is there any way this could be an SDT? I recently had sex with a woman who has herpes although she has never had an outbreak after her initial exposure 10 years ago. Could these freckles that I now have which are appearing in the region between my belly botton and lower pubic area (almost touching my penis) in any way be reflective of herpes?
